The hardware hacking village at Toorcamp provided space and tools to work on hardware. It was interesting to see what hardware hacks people had brought to work on. One example is [Owen]‘s Nibble Node.js Widget. The widget combines the popular node.js platform and custom hardware to create a node for the “internet of things.” The hardware consists of a Arduino Pro Micro, a bluetooth module, a LCD display, and a speaker in a laser cut box.
By using a custom package in node.js, the Nibble becomes an object which can be controlled by its methods. This allows for the developer to push messages to the display and control the device without worrying about the details of the hardware. Since node.js is designed for web applications, it’s simple to make the device controllable from the web.
[Owen] also wrote an emulator for the DCPU from the upcoming game, 0x10c. DCPU assembly is passed in from node.js, which compiles it and sends it to the Nibble. The device can then run the application using the DCPU emulation, which also allows for control of the display and the speaker.
There’s a lot of neat things that can be done with this minuscule cube, and [Owen] plans to release an NPM package for the node.js code.
